Purpose
BookAI is an AI book generator for writers who want to complete a book quickly. Its core workflow is "one sentence in, a whole book out": the user provides a premise (for example, "a lighthouse keeper begins receiving letters from a shipwreck in 1911"), and BookAI handles the complete creation pipeline from outline to finished manuscript.
Main Capabilities
- Chapter Outline: Automatically generates a chapter structure based on the premise described by the user.
- Long-form Writing: Writes the main text section by section, maintaining consistency in the story or argument; any chapter can be edited or regenerated.
- Cover Generation: Can generate book covers and can regenerate cover images.
- Audiobook Narration: After existing manuscript text is available, uses AI speech to record audiobooks for chapters; audio tracks are bound to the book, and readers can listen on the public page.
- Export and Publishing: Supports export to publication-grade PDF and EPUB; users can also continue writing in the browser editor and generate a public page with a unique URL for the book.
- Genre and Style Control: Supports fiction and nonfiction; users can set genre, tone, target readers, and custom instructions so the draft fits their own voice.

Applicable Scenarios
Suitable for drafting and completing novels, memoirs, business books, guides, and educational books; suitable for writers who need to quickly produce long-form content.
Limitations and Copyright
- The free plan includes 50 pages per month, allows writing only 1 book at a time, and books are public (including a public SEO page).
- Paid plans (after a 2-day free trial, $30/month) include 5,000 pages per month, 1 hour of audiobook narration, up to 500 pages per book, and support fast generation, PDF and EPUB export.
- Higher-tier plans provide 10,000 pages per month, 3 hours of narration, up to 1,000 pages per book, unlimited books, and priority support.
- The highest-tier plan provides unlimited pages, unlimited audiobook narration, up to 5,000 pages per book, all models and voices, and Audio Studio, but is subject to fair use terms.
- New books are public by default so they can be read and indexed; paid plans can set them to private; public books appear in the /books library and have a stable canonical URL.
- Users retain the rights to the manuscripts they create and export (subject to the terms of service); it is recommended to treat AI as a drafting assistant, edit it yourself, verify facts, and then publish under your own name.
